Specification of Letters Patent.

Patented May 2', 191,1.

Application4 filed April 5, A1910.4 Serial No. 553,489.

fb all whom it may concern:l

Be it known that I, WILLIAM L. HOWARD, a citizen of the United States, and a resident loi. Trenton, inthe county 'of' Mercer and 5.State of New Jersey, have invented a new and Improved Vehicle-VVheel, of which the following is a full, clear, -and exact description. v

' This invention relates ,to certa-in improvel0 ments in vehicle wheels, and more particu-A larly toa means employedifo detachably securing the tire-'carrying rim' to th'e telly ofthewheel. l My vehicle wheel o er'ates upon the same l5 general principle .as the wheelsidisclosed in my prior Patents, Nos. 929,437 and 932,862, but involves certain improvements in the 'cams and themeans for mounting, operating and controlling the same. I

20 yReference is to be had to.- the accompany# ing drawings,l forming a. part of this specifi'- cation, in which simi ar charactersof reference indicate corresponding parts in all the gures,:and in whichv ,2 6 l Figure 1 is 'a sideelevation of-a wheel 'constructed in aocordancewith my invention, a portion thereof bein shown in section; Fig .2 is an edge v"View "o aportion of the whee thethereof being removed; Fig. 3 is a 80 `transverse section on the line 3--3 of Fig. 1 and on an enlarged slc'aleyandFig. 4 1s a view -s'i'milarto a. portion of .Fig 1,v but showing the Vgripping section in `released 'po` j sition..", p l :itl` In my improved wheel, I employ any su1t' able forni of fell 10, connected to a hub 11 by'v anysuitable crm of spokes or connecting'm'eans12. A- 13 encirclesthe telly A and is' spaced therefrom, lthe said rim being 4qjof 'an .suitable character, inthe form illus-A trate bein' of a type'commonly known las a u. demounta legrim, and adaptegl to", carry 'a nematicor other, form off-resilient tire'.

y invention relatsto themes-'ns forde- -4'5`tachably'securingthe'rimto the telly, and m the fi'm illustra-ted 'it includes two substan- Itiallji'el;annel-shape'd membrsj`14 and 15.l Theliannel 14 'has its' 'web' rigidly secured to?" e peripheryjof the ,fell and.I has its.

y 50, `s extending'. herefiom in p planes.-v The channel 15 is 'held against-rotationin respect to the shaft substantially parallel planes. lThe channel l 15 has its web facingkoutwardly and its flanges extending inwardly'toward the center of the wheeland'- in substantially parallel sli htl narrower than the channel 14, so that t e ormer may fit within the latter, as illustrated particularly .in Fig'. '3, The two channels are rela# tively movable both circum'feentially-'and radial1y,f andsthis movement operates to ef- 'fect the 'gripping action. To' move the channel mem ver or gripping'lnember 15, an'operating mechanismI 1s` provided at one end thereof and a, lurality-of pairs of cams are mounted within the two channels, so as to coperate and force'the member 15 radially when the latteris moved longitudinally ,by the operating mechanism. The operating mechanism includes 'a boltorshaft 11, ex# tending transversely through the channel 14 70 and supported byfthe side flanges of the latter.,-V

Within the channel 14 and also -within the channel l5, is a bearing block 17, formed-of two detachably connected sections; one of which has two wings or flanges 18, V18, through which lthe bolt passes, to 4 revent the lon tudinal 4movement of the earng block alhlng the channels. A screw bolt 19 is mounted within this' bea-ring lblock and is held against longitudinal movement Ain r'espect thereto by a collar 20 'at-one end of the bearing block, and abevel pinion 21fat'the op otite end. This .bevel pinion 21 comes adjacent ythe bolt 16 Vand intermeshes' with a 85 bevel pinion 22 mounted on the latter, so that by rotating the bolt 16, the screw bolt 19 may also be rotated. The pinion 22 is 6in any suitable. manner, as forinsta-noe,

a .squared shoulder or bolt, and the bolt ferably lrotated by means of any suitab 4form of wrench or other tohl, which may be appliedV to anouter squared head or end' 23 atene end of' the-bolt and outsideof-,S the channel 14.-4 For locking the bolt against rotation, a notched collar 24 may be mounted ladjacent the Ihead, and a s ring-pressed catch 25 may engage within-t enotches olf. the collar. 'Ifhe outer end of the catch extends 100 beyond the bearing` block and has threaded engagement with the gripping member, so

as to move the latter longitudinally upon the i rotation of the screw bolt. Brazed or otherwise rigidly secured to the inner surface of the vveb'of the channel 15,

are a pluralityy of blocks-26, each presenting a beveled or inclinedunder surface constituting a cam.' For co-acting with these cam blocks, the outer surface of the Web of the channel-14 is provided With a set'of blocks 27, the outer vsurface of each of Which is inclined or Ibeveled to form a cam surface.l

These cams are `so disposed in respect to each other, that by va longitudinal movement of the channel 15 in one direction, each cam A26 is caused to ride up on to' its corresponding camV 27 so as't force the channel 15 out-ward f radially. Alongitudinal movementA of the channel 15 in the opposite direct-ion, permits the return radial movement of said channel. For insuring this return movement,` certain of the -cam blocks 27 for instance, the terminal ones, also haveinclined or beveled .under surfaces and the web of the' channel-15 has tongues vor flanges 28 struck inwardly therefrom and adapted to engage with these linclined under surfaces. As the channel member moves to bring the cam blocks 26 down olf the cam blocksV 27, thetongues28 positively draw the channel 15 inwardly.

, For insuring the positive gripping f the -rim -by the channel member vor arlppng member 15, the latter adgacent certain of the cam blocks 26, for instance the intermediate ones, may have bayonetslots 29 for' receiving pins or studs 30 on the rim,` substantiallyas .disclosed in my prior patents above re- V:terred to. yThe gripping member or channel 15 extends around slightly* more than onehalf the circumferenceof the Wheel,:andthe cams are so.- proportioned that all portions. ofthe gripping member m'oveou'tWai-d radi-` ally-to' the same extent when said member is moved circumferentially. Along the re-.

maining approximately one-half circumfer- 'enc'e' of the Wheel, the channel 14 is provided with an outer cover plate or Wall 31, which 'may be brazed or otherwise rigidly secured tothe outer edges of. the flanges 'of said channel. This`cover plate presents a surface for engagement with the inner surface of the rim and lies ,in an arc of the same circle as thc web ofthe channel 15 when the latter is in extended posit-ion. l

For counterbalaneing theweight of the cam blocks 2G or 27, al block or Weight 32 may be secured Within the channel 14 diame-trically opposite to the center of the gripping member. The plate 31 and the weight 32v may have an openin therein for the reception of a stud or pro]ection 33'on the rim', which projection will insure the proper positioningl of the rim and will prevent it from moving-axially or circumferent-ially should the gripping member be-left somewhat loose. The channels, cam blocks and other operating parts may be formed of any' suitablev material desired. As illustrated, the inner cha el lfi-sprov-ided with van outer coveringp ate 34 of brass, which protects the channel against Water which might rust it, and it also presents a good gripping surface for engagement with the inner surface of the rim,

Having thus described my invention, I claim as new .and desire' to secure by Letters Patent: l I l 1.
